SUPPORTING INSULATOR.

Application fled July 22, 1922. Serial R'o. 576,758.

To all whom it my camera:

Be it known that I, WILLIAM I). KYLE, a

citizen of the United States, and resident of object to provide a device of thiskind oi simple construction and with special adapt ability for securing a plurality of wires thereto.

The invention further consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings: Fig. 1 is an elevation view partly in section, of a device embodying the invention; Fig. 2 is a detail sectional view taken on the line 2-2 of Fig. 1; Fig. 3 is a section taken on the line 3-3 ot'Fig. 1; Fig. i is a vertical sectional view of the insulator with a modified form of attaching member.

In the drawings the numeral 5 designates a block of insulating material, such as porce lain, provided with spaced transversely disposed wire-receiving openings 6 and 7, an annular wire-receiving groove 8 in a plane disposed between said openings, a front end wire-receiving groove '9, a flat base 10, and a longitudinally extendingcentrally disposed slot -ll.

The metal member for attaching the insulator to a support may be of various forms but in each instance includes a part 12 fitting within the slot 11 and secured thereto by a suitable cement 13 in case the block is made of porcelain. This part 12 is provided with openings 14 and 15 registering with the openings 6 and 7 and of greater diameter, and a ringldoi cement having suitable insulating properties is formedabout these openings 14 and 15.

In Figs. 1 to 3, inclusive, I have shown the parts 12 as forming the arms of a bracket 17 provided with openings 18 for the use of screws or bolts to secure it to a support, while in Fig. 4 I have shown the part 12' as forming an extended shank of a threaded attaching member 19, such as a lag screw or bolt, to secure the insulator to a support.

The grooves on each block and the open-- ings therein permit of a variety of arrangements of supply wires, branch wires and tie wires being used, and the part 12 projecting as it does into the head of the insulator provides a strong reinforcement'for the same.

While I have shown the block form of insulating material, such as porcelain, it will be understood that this block may be formed of other insulating material, such as molded insulating material, so that the metal parts i may be secured in position in such material during the process of molding, in which case a cement filler is not necessary.

What I claim as my invention is:

1. In a line conductor support, the combination of a block of insulating material provided with a longitudinally extending slot, a transverse opening and an exterior wire-receiving groove, and an attaching member having a part secured within said slot and provided with an openingregistering with. and of larger diameter than said transverse opening.

2. 'In a line conductor support, the combination of a block of insulating material having s aoed transverse wire-receiving openingIa centrally disposed longitudinally extending slot, a groove disposed within a plane lying between said openings and' 'a'n attaching member having a part mounted in said slot and provided with openings registering with but larger than the openings in said block, and insulating material covering the exposed sides of the openings of said attaching member.

3. In a line conductor support. the combination of a block of insulating material provided with spaced transverse wire-receiving openings, an annular wire-receiving groove lying in a plane between said openings,. a wire receiving groove at the head. end of said block, and a centrally disposed longitudinally extending slot, an attaching member having a part mounted in said slot with openings registering with said transverse openings and of greater diameter than said openings, and insulating material surrounding the edges of the openings in said member,

In testimony whereof I afiix my signature.

WILLIAM D. KYLE.
